Computer Assisted Personal Interviewing (CAPI) is the process of using portable
computers and data collection software to interview subjects. Quality CAPI software, such as Survey System will reduce errors and the time
required to collect data.

CASI

Computer Assisted Self-Interview (CASI) is the process
of having subjects fill out surveys about themselves on a computer.

Survey
System has been used on Tablet PCs in clinical environments where patients filled out
surveys about themselves.

Patients who reported not being comfortable with computers also
reported that filling out surveys with Survey System was easier than the paper
portion of the survey.

Survey System also provides locking mechanisms to stop the subject from
accessing other data when the tablet is in their possession.

A quality CAPI solution must provide an efficient way to create
questionnaires and collect data in those questionnaires. It should
not be intrusive on the interviewing process (i.e. a lap top being placed
between the interviewer and interviewee). It should also be as
intuitive if not more intuitive than collecting information on paper.

Survey System's WYSIWYG design interface is comparable in both time and
complexity to creating a survey with a word processor. The tight
integration with a Tablet PC makes the interviewing process similar to two
people sitting across from each other where one is holding a clipboard and
recording information.

Survey System goes beyond the simulating paper surveys paradigm in
several ways.

While other CAPI solutions "RUN ON" a Tablet PC as all windows
applications do, Survey System was built from the start with the Tablet PC in
mind. To understand this difference,
